Sound and acoustic products such as sonar and side scan sonars and positioning systems are the major shareholders in the market while the Echosounder has the highest growth potential, followed by profilers and tide gauges.

UCSD undergraduate students spent the past three years identifying and correcting the blunders as well as adding all the multibeam echosounder data archived at the National Geophysical Data Center in Boulder, Colorado.

Prior to deployment of video 4-camera arrays, the survey sites' bottom type was assessed with the ship's echosounder to determine presence of bottom features (reef structure) or above-bottom return signals (fish).

To this end, we used multibeam echosounder data to generate metrics that describe the seafloor: backscatter strength at normal and oblique incidence angles, the variation of the angle-dependent backscatter strength within 10[degrees] of normal incidence, the scintillation of the acoustic intensity scattered from the seafloor, and the seafloor rugosity.
